SASH-FASTENER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed September y gelial 17 T0 n/Zl whom, it may concern.-

Be it known that I, DANIEL WILDE, acitizen of the United States, residing at WVashington, in the county of Washington and State of Iowa, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to an improvement in sash fasteners for windows, and the object of my invention is to provide means whereby both sashes are'locked by separate means, and which will prevent a window from being raised or lowered when in locked position, as the force exerted to push the lower sash up or pull the upper sash down only tends and causes the locking means to get a firmer grip on the window sash.

My invention relates to certain other novel features of construction and combinations of parts, which will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view showing the invention applied to a window frame, Fig. 2 is a view showing the inside bead removed, Fig. 3 is a sectional view showing the locking mechanism in elevation, Fig. 4 is a horizontal sectional view on the line 44 of Fig. 2, Fig. 5 is a view of one of the locking means and Fig. 6 is a modification.

A, represents the window frame, and 1, 1 the window sashes.

B, is the locking plate, preferably made of sheet metal, and which is folded over upon itself to form a hollow casing for the locking means. The plate being secured to the window frame in any suitable manner, but I have shown it secured by means of screws 2, 2. The turned over portion of the plate is cut so as to form lips 3, 3 which lips are provided with slots, 4, 4.

The locking means 5, 5 are provided with pins 6, 6, on each side thereof, which are received in the slots 4, and a spring 7 is connected to the locking means, and the ends of the spring are received in the recesses 8, 8 formed in the locking means. The spring being held by a projection 9, which is an integral part of the plate B, and in this way the spring is held so as to respond to the least pressure exerted against it.

The locking means are made in different shapes, and I will first'describe the locking means for the inner sash. This locking means is preferably made V-shaped, and terminates in a sharp point 10, which end is forced against the window sash by the slide, which is made L-shaped, but the bottom portion tapers from the handle down to a sharp point 12, in the form of a wedge, this sharp point is received back of the locking means, and when it is desired to lock the window, the slide is pushed downwardly, thereby forcing the sharp point 12 back of the locking means and driving it forward against the window.

The locking means for the outer sash, is made preferably L-shaped, and the arm 13 of the locking means is offset as at 14, and is received through the slot 15 in the plate, into the groove 16 in the window frame. The parting strip 17 is cut away, so as to receive the upturned end 18, which is ground to a sharp point 19, which comes in contact with the sash when in locked position. This locking means is operated the same way as the one for the inner sash, and it will not be necessary to repeat the description of the operation. V

The entire locking means are covered over and out of sight by the cap plate, 20, which takes the place of the inside bead, and is provided with elongated openings 21, 21, to receive the operating slides 11, whereby to operate the locking means.

In the modification shown in Fig. 6, I have shown the ends or gripping ends 10 and 19, made slightly rounded as at 22, and provided with corrugated rubber gripping means 23, which will be forced against the window sash and prevent the up or down movement of the sash when in locked position. Of course, the rubber need not necessarily be corru gated, as it could be made smooth, and would give the same result.

From the foregoing it will be readily seen, that I have provided a locking means which can be used on any kind of window, and at the same time one which will hold a sash in any position, and either sash can be raised or lowered without interfering with the other.

The locking means instead of being covered by a cap plate 20, might simply have the inside bead of the window frame grooved out, whereby the locking means could be placed thereunder. Again, my invention consists of few parts, and are all on one side of the window frame, easy to manipulate, and one which will be cheap to manufacture.

It is evident that many slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my in- IIO VGBtiOIl, and hence I do not Wish to limit my- I self to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A sash fastener comprising locking means, a spring connecting the locking means together, and slides for throwing the locking means in locked or unlocked position.

2. A sash fastener comprising locking means, a spring connecting the locking means, and recesses in the locking means for the ends of the spring and means for operating the locking means.

3. A sash fastener comprising a plate folded over upon itself forming a hollow casing, said plate having slots formed therein, locking means received in the slots, and means for operating-the locking means.

4. A sash fastener comprising a plate folded over upon itself forming a hollow casing, said plate having slots formed therein, looking means having pins formed thereon, said locking means received in the casing and the pins in the slot, and means for operating the locking means.

5. A sash fastener comprising a plate, and locking means for locking the upper and lower sash of a Window, the plate having slots formed therein, said locking means received in the slots, one of the locking means of a greater length than the other, and means for operating the locking means to hold the windows in locked or unlocked position.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL VILDE.
